ATTACHMENT FOR SEWING MACHINES.

SFECIFICATION forming part of Letters Patent No. 334,118, dated January 12, 1886.

Application filed April 11, 1885.

To aZZ 2071,0722, it may concern:

Be it known that I, ELMER S. HARRIS, of Haverhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Attachments for Sewing-Machines, of which the following is a full, clear, and exact description.

This invention relates to an attachment for sewing-machines, more particularly for sewing-machines used in the manufacture of turned boots and shoes, and in which boots or shoes the sole is first channeled in any of the usual ways, and the lip made by such channeling turned back, as shown, for instance, in a pending application of mine and L. M. Nichols, filed December 4, 1884, Serial No. 149.500, for Letters Patent on improvements in soles for boots and shoes; and the invention consists of the construction and arrangement of a post or standard of asewing-ma-chine, on the upper end or edge of which a boot or shoe, while being operated upon by the machine, rests, is supported, and guided in such manner that such supporting and guiding edge of the post or standard can be regulated and adjusted as to itsheightanditsproper position horizontall y in relation to the needle and the other portion of the sewing mechanism of the machine for the proper operation thereof in sew ing the boot or shoe, all substantially as hereinafter fully described.

In Figure 1 of the accompanying plate of drawings is shown in partial side view and partial vertical section a post or standard of a sewing-machine constructed according to this invention, showing the needle of the machine in side view, and also showing in detail section a sole and upper of a boot or shoe in position for operation thereon. Fig. 2 is a plan view of Fig. 1; and Fig. 3 a cross-section on line 3, Fig. 1, showing also the bedplate in detail section.

In the drawings, A represents a post or standard of a sewing-machine, substantially as used in sewing-machines for sewing boots and shoes, except as to this invention. This post or stand A is divided into three parts, B, C, and D.

B is the base by which the post is attached and secured to the body or bed plate E of the machine, having a horizontally-proj ecti n g por- Serial No. 161,916. (No model.)

b freely passes and screws into the plate E, by

which screw the part B is secured to the bedplate, and yet is free to be moved forward and backward on the bed-plate when desirous of adjusting the position of the upper edge of the post in the operation of the sewing-machine.

Ois the middle part of the post, circular in cross-section and fitting within a vertical socket, K, in the upper end, (I, of the part B, and to turn freely therein, and provided with a screw-threaded extension, L, which screws into the part B atf. to the right or left by its screw L lowers or raises the part 0 on the part B, and when in the position desired it is secured from accidental movement by a set-screw, g, screwing into the side of the part B and against the screw L. The upper part, D, has a round tenon or extension, h, on its lower end, adapted to fit and freely turn within a socket, Z, in the upper end, m, of the middle portion, O, and resting by its shoulder a on such upper end, m.

g isa set-screw screwing into the portion 0, and arranged to screw against the extension h of the part D, by which the upper part, D, is prevented from accidental movement. The upper part, D, from its lower end gradually diminishes in size toward its upper end, i, which upper end extends or projects laterally from and beyond the central portion of the post, as shown in the drawings, for its upper end to be in a position for more convenient use in the operation of the machine. The upper end is reduced to a thin plate or knife-like edge, .9, its upper surface being straight and in a horizontal plane,preferabl y. On this edge 8 the sole M of the bootor shoe rests and is guided to the needle in the operation of the machine, as shown in Fig. 1, the shoulder or groove t in the sole, formed by the turned-back lip, 24, of the sole, resting on the edge 8, which guides it to the needle N,which passes through Turning this portion 0 the upper P and the sole M just behind the end 1; of the edge 8.

The object of making the post in three parts, as described, is to enable the edge or rest 8 to 5 be raised or lowered for its proper adjustment as to its height and its proper position in relation to the needle and its movements in making the stitch in the material to suit varying thicknesses of soles and the proper guid- 3 ance of the sole to the needle-as, for example, if the sole is thin the edge 3 should be raised higher than if the sole is thick. This adjustment is secured by simply turning the parts D in their respective sockets, for instance, as 5 follows: Loosen both set-screws g g, and hold the edge .9 at the desired point horizonta-llyin reference to the needle, and then turn the middle portion to the right or left, as it is desired to lower or raise the edge 8, and when at the v desired height s rewin the set-screw g, which secures the middle portion, 0, from movement; then, if need he at ju-t the edge 8 by turning the portion D to the right or left and screw up its setscrew q to secure it from movement. To 5 adjust the edge 8 forward or backward to bring it in line with the needle, loosen the screw b and move the post along the bed-plate as desired. and when the edge sis in the right position screw up said screw (2, which will sea cure the post from movement on the bed-plate, swinging or lateral movement on the bed-plate being prevented by the tongue-and-groove connection with the bed-plate described and shown. The upper part, D, can be attached 3 to the middle part, O, by a screw, in lieu of the middle part, 0, to the base B, but as described and shown is preferable. The post can be connected to the bed-plate or support permanently, or to prevent lateral movement in other ways than as shown; but the way shown is simple and practical. supported in any suitable manner on any part of the machine or independent thereof.

In lieu of set-screws to secure the parts together to prevent their movements, other means can be used; but set-screws are sufficient and satisfactory.

4 Having thus described my invention, what I claim is- It can also be 1. A-post or standard of a sewing-machine, made in three parts, B, O. and D, one part. B, of which is secured to the bed-plate or table of the sewing-machine, the part D having a rest or guiding-edge, 8, said part D and the part 0 being adapted to be connected to said part B and to each other by screw-and-swivel joints, and provided with means for securing them from movement, all substantially as and for the purpose specified.

2. A post or standard of asewing-machine, made in three parts, B, G, and D, onepart, B, of which is connected to the bed-plate or table by a tongue-and-groove joint and provided with a slot and set-screw, the part D having a rest or guiding-edge. 8, said part D and the part 0 being adapted to beconnected to said part B and to each other by screw-andswivel joints, and provided with means for securing them from movement, all substantially as and for the purpose specified.

3. A post or standard fora sewing-machine, made in three parts, B, C, and D, one part, B, of which is secured to the bed-plate or table of the sewing-machine, the part 0 adapted to screw into said part B, and secured therein by a setscrew, g. and the part D, provided with a rest or guiding-edge, 8, adapted to swivel in said part 0, and secured therein by a setscrew, q, all substantially as and for the purpose specified.

4. A post or standard ofasewing-machine, made in three parts, B, G, and D, one part, B, ofwhich is connected to the bed-plate or table ofthesewing-machine by a tongue-and-groove joint, and provided with a slot, a, and screw b, the part G arranged to screw in said part B, and secured therein by a set-screw, g, and

the part D provided with a rest or guidingedge, 8, adapted to swivel in the part 0, and secured therein by a set-screw, q, all substantially as and for the purpose specified.

In testimony whereof I havehereunto set my hand in the presence of two subscribing wit- DGSSQS.
